The present invention relates to electric connector field, particularly to a kind of full-shield electric connector.
Background technology
Electric connector is the part used extensively in electric signal transmission, with constantly widening for its application field, is electrically connected
Device, which can only complete common electric signal transmission, far can not meet demand, work(of the various electrical equipments all to electric connector
The indexs such as energy, size, waterproof and dustproof, signal transmission quality propose more harsh requirement.Wherein signal transmission quality is even more
Become and the good and bad important indicator of electric connector is weighed in some fields.
In traditional electric connector, the shielding construction design to electric connector is come from metal shell and tail accessory mostly
Consider, for example, circular shield electric connector, it is, when tail portion of connector installs cable, to be covered by internal copper shield line
The metal shell of gauze screen and connector on cable compresses conducting, so that the purpose to reach shielding external interference.
The shielding of above-mentioned electric connector is realized due to being only the metal shell by electric connector, therefore it is only capable of reality
Existing electric connector is overall relative to extraneous shielding, that is, is only capable of resisting the interference outside connector.But for some electrical connections
For device, interfering between its internal contacts will even exceed the interference outside connector, if shielding construction is only capable of
The interference outside electric connector is resisted, it is clearly that can not meet use requirement.Therefore, the shielding knot of current electric connector
The problem of structure has not comprehensive shielding, shield effectiveness difference.
The content of the invention
It is incomplete to solve existing shield electric-connector shielding it is an object of the invention to provide a kind of full-shield electric connector
The problem of face, poor shield effectiveness.
In order to solve the above problems, full-shield electric connector of the invention uses following technical scheme：Full-shield is electrically connected
Device, including metal shell, dielectric member and contact part, the dielectric member include internal layer fixing assembling together
Insulator and outer insulator, are provided with inner shield set between inner insulator and outer insulator, contact part includes assembling
Inner layer contacts part and the outer layer part being assemblied on outer insulator on inner insulator.
Positioning key is equipped with one in the inner insulator and outer insulator, another is equipped with and positioning key
The featherway of cooperation, is coordinated between outer insulator and inner insulator by the positioning key key, the respective end of inner shield set
Provided with the keyway coordinated with positioning key.
The dielectric member also includes fixed insulation body, and fixed insulation body is fixed in metal shell and from front to back
Inner insulator is compressed, inside and outside layer insulator is fixed together by fixed insulation body.
The fixed insulation body is fixed in metal shell by jump ring.
One in the outer insulator and metal shell is sold provided with guiding, and another is provided with guiding groove, outer layer
By guiding pin and guiding groove location fit between insulator and metal shell.
Rear end on metal shell inwall in dielectric member is provided with the otic placode that extends internally, and dielectric member passes through institute
The screw set on otic placode is stated to be fixed in metal shell.
Because the dielectric member of the full-shield electric connector of the present invention includes inner insulator fixing assembling together
Inner shield set is provided between outer insulator, and inner insulator and outer insulator, contact part includes being assemblied in
Inner layer contacts part and the outer layer part being assemblied on outer insulator on inner insulator, it is therefore, when in use, interior
Housing can play a part of being mutually isolated between inner layer contacts part and outer layer part, connect so as to be shielded by metal shell
The interference outside device is connect, interfering with each other between the contact inside and outside it is isolated by inner shield set, and then realize electricity
The comprehensive shielding of connector, the problem of solving not comprehensive existing shield electric-connector shielding, shield effectiveness difference.

Embodiment
The embodiment 1 of full-shield electric connector, as shown in Figure 1-2, the full-shield electric connector include metal shell 11, absolutely
Edge body component and contact part.
Metal shell 11 is that the electric connector in circular shell, therefore the present embodiment is round electric connector.Need especially
Guiding pin 12 is equipped with the wall for being pointed out that metal shell 11, guiding pin 12 is assemblied in metal shell 11 using thread forms
On, its inner penetrates metal shell 11 and extend into inside metal shell 11.
Dielectric member includes inner insulator 13 and outer insulator 14, in the present embodiment, except above-mentioned internal layer is exhausted
Beyond edge body 13, outer insulator 14, dielectric member also includes fixed insulation body 15.Inner insulator 13 and outer insulator
Isolated between 14 by inner shield set 16, the specific assembling structure of dielectric member is as follows：On the periphery wall of outer insulator 14
Provided with keyway, positioning key 17 is equipped with keyway, positioning key 17 is round key, and the periphery wall of inner insulator 13 is provided with and internal layer
The corresponding featherway of positioning key 17 on insulator, inner shield set 16 on also be provided with the corresponding keyway of positioning key 17, in this reality
Apply in example, the keyway on inner shield set 16 is actually to be located at the opening that profile thereon is adapted to positioning key 17, fixed insulation
Body 15 is enclosed on the front portion of inner shield set 16 and is securely fitted in by jump ring in metal shell 11, first that internal layer is exhausted during assembling
